What you should pay attention to when handling lithium batteries

To keep lithium-ion batteries efficient and avoid potential damage or fires, keep the following points in mind when storing and charging them:

Store the battery separately from the device

Remove the lithium-ion battery from the electrical device and store it separately to avoid chemical reactions and damage to the device.

No unattended charging without battery protection box

You should not leave lithium-ion batteries unattended during charging. Unless you have a fireproof box in which the battery can be charged with the lid closed and through a cable guide. By the way, the best case is to charge the batteries at room temperature.

Select a cool and dry storage location

Store the batteries at temperatures between 6 and 15 degrees Celsius to avoid overheating. Make sure that the storage location is dry,
to prevent contact with water.

Avoid high temperatures

Do not store the batteries in high temperatures, or direct sunlight to avoid damage. Keep a minimum distance of 2.5 meters from other combustible materials if no automatic extinguishing systems are available. Accordingly, a garden shed, for example, is not an ideal place to safely store or charge your e-bike, or power tools.

Protection from mechanical damage

Make sure that the batteries are protected from shocks and damage to prevent short circuits. Since it is sometimes not so easy to assess the condition of the battery, the lithium battery should be charged and stored in a fireproof box.

Check the state of charge regularly

Check the state of charge regularly, especially during longer storage periods. An occasional short charge every 3 to 4 months can prevent deep discharge.

Store damaged rechargeable batteries safely

Store damaged or defective rechargeable batteries in special safety containers until they can be disposed of. Keep them in a segregated area.

Prevent deep discharge

Store batteries at 50 to 70 percent capacity to prevent deep discharge. It can occur if the battery is completely discharged and not recharged within 1-2 weeks. A typical scenario: discharging the battery almost or completely in the fall without recharging it afterwards. In the spring, the battery may then be unusable and pose a high potential hazard during the charging process.

Follow manufacturer's instructions

In addition to our tips, follow the manufacturer's storage instructions and information on the product data sheets. In the best case, always use the original charger.
